  1. Position bucket (1) on the ground. Position O-ring seals (2) from the pin joint onto the flanges of bucket (1).


    Illustration 3g01209896

    ------ WARNING! ------

    When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death.


    Note: Threaded rods cannot be used with hydraulic cylinders as tooling.

  2. Attach a suitable lifting device and Tooling (B) to Tooling (A). Attach Tooling (A) to pin assembly (4). The weight of Tooling (A) is approximately 137 kg (300 lb).

  3. Remove bolt (3). Use Tooling (A) in order to remove pin assembly (4). The combined weight of Tooling (A) and pin assembly (4) is approximately 170 kg (375 lb).

    Note: Reposition the suitable lifting device as pin assembly (4) is removed.

  4. Remove O-ring seals (2) (not shown).
